You can be injured and your vehicle could be
damaged if you try to do service work
on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused.
If you use
the wrong fasteners, parts can later break
1 or fall off. You could be hurt.
Adding Equipr- ~ I - ’; to t!- -I Out ‘de of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it.
This may cause wind noise
and affect windshield washer performance. Check with
your dealer before adding equipment to the outside of
your vehicle. Use regular unleaded gasoline rated at 87 octane
or higher. At a minimum, it should meet specifications
ASTM D4814 in
the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have
been developed by the American Automobile Manufacturers Association (AAMA) for better
vehicle performance and engine protection. Gasolines
meeting the
AAMA specification could provide
improved driveability and emission control system
protection compared to other gasolines.
Be sure the posted octane is at least 87. If the octane is
less than 87,
you may get a heavy knocking noise when
you drive.
If it’s bad enough, it can damage your engine.
If you’re using fuel rated at 87 octane or higher and you
hear heavy knocking, your engine needs service. But don’t worry if you hear a little pinging noise when
you’re accelerating or driving up a hill. That’s normal,
and you don’t have to buy a higher octane fuel to get rid
of pinging. It’s the heavy, constant knock that means
you have a problem.
Downloaded from www.Manualslib.com manuals search engine If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to operate on fuels that meet
California specifications. If such fuels are not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator lamp on your instrument panel may turn on and/or your
vehicle may fail a smog-check test. If this occurs, return
to your authorized Chevrolet dealer for diagnosis to determine the cause of failure.
In the event it is
determined that the cause of the condition is the type of
fuels used, repairs may not
be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT); ask your service station operator whether or not his fuel
contains
MMT. General Motors does not recommend the
use of such gasolines. If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may turn on.
If this occurs, return to your authorized
Chevrolet dealer for service.
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system
to
function properly. Therefore, you should not have to
add anything to the fuel. In addition, gasolines
containing oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines
if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and
also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.

Downloaded from www.Manualslib.com manuals search engine As shown in the chart, SAE 1OW-30 is best for your
vehicle. However, you can
use SAE 5W-30 if it’s
going
to be colder than 60 “F ( 16 ” C) before your
next oil change. When it’s
very cold, you should use
SAE 5W-30. These numbers on an oil container show
its viscosity, or thickness. Do not use other viscosity
oils, such as
SAE 20W-50.
I NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure to use the recommended oil can result in engine damage not
covered by your warranty.
GM Goodwrench@ oil meets all the requirements
for your vehicle.
If you are in an area where the temperature falls
below
-20°F (-29”C), consider using either an
SAE 5W-30 synthetic oil or an SAE OW-30 oil. Both
will provide easier cold starting and better protection for your engine at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. Your dealer is ready
to advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:

Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as
frequent driving in stop-and-go traffic).
You operate your vehicle in dusty areas or
off-road frequently.
You frequently tow
a trailer or use a carrier on top
of your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. If any one of these
is true for your
vehicle, then you need to change your oil and filter
every 3,000 miles
(5 000 km) or 3 months -- whichever
occurs first.

Downloaded from www.Manualslib.com manuals search engine If none of them is true, use the long triphighway
maintenance schedule. Change oil and filter every
7,500 miles (12 500 km) or 7.5 months -- whichever
occurs first. Driving
a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be unhealthy for your skin and could
even cause cancer? Don't let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil. (See
the manufacturer's warnings about the use and disposal
of oil products.)
Used oil can be
a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don't ever dispose of oil
by putting it
in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.
Air Cleaner
Operating the engine with the air cleaner off can
cause you
or others to be burned. The air cleaner

4. Replace the cover and the screws.
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every
15,000 miles
(25 000 km) if the vehicle is mainly driven under one
or more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90 OF (32 O C) or higher.
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If
you do not use your vehicle under any of these
conditions, change the fluid and filter
every
100,000 miles (166 000 km).

Downloaded from www.Manualslib.com manuals search engine How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Chevrolet dealership Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading on
the dipstick.
NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading
if you check your
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level
if you have been driving:
When outside temperatures are above 90 "F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at
normal operating temperature, which is
180°F to
200°F (82°C to 93°C).
See "Checking Transmission
Fluid Hot" in the Index.
Checking Transmission Fluid Hot
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above
50°F (10°C). If it's colder than 50°F (lO°C), drive
the vehicle in
DRIVE (D) until the engine temperature
gage moves and then remains steady
for 10 minutes.
Then follow
the hot check procedures.
Checking Transmission Fluid Cold
A cold check is made after the vehicle has been sitting
for eight hours or more with the engine
off and is used
only as a reference. Let the engine run at idle for
five minutes
if outside temperatures are 50°F (10 "C)
or more. If it's colder than 50°F (lO"C), you may have
to idle the engine longer. Should the fluid level be low during
a cold check, you must perform a hot check
before adding fluid. This will give you a more accurate
reading of the fluid level.

Downloaded from www.Manualslib.com manuals search engine How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transmission fluid to use. See “Recommended
Fluids and Lubricants” in the Index.
Add fluid only after checking the transmission fluid
while it is hot. (A cold check is used only as
a
reference.) If the fluid level is low, add only enough of
the proper fluid to bring the level up to the
HOT area for
a hot check. It doesn’t take much fluid, generally less
than one pint
(0.5 L). Don’t overfzll.
NOTICE:
We recommend you use only fluid labeled
DEXRON@-111, because fluid with that label is
made especially for your automatic transmission.
